Lesson 5

Navigation - Lesson 5

Teacher Resources:

Primary Goal
:
Introduce students to the history of charts and maps and how they are used today

Topic: Bearing Triangulation

Primary Goal
:
Students will learn how to determine their location by triangulation. They will accomplish this by taking bearings of surrounding objects. This lesson will build on their work with the hand-bearing compass and demonstrate one of the primary uses of a compass.

Lesson Objectives
:

·
Understand the reasons why you would need to determine your location

·
Understand how you would use a compass to take bearings of objects around you

·
Learn how to transfer those bearings onto a chart using navigation tools

Lesson Outline
:

I.
Piloting

a.
This is a great opportunity to give an overview of the 3 different types of navigation

i.
Electronic Navigation – used inland but critical offshore

ii.
Celestial Navigation – used primarily offshore

iii.
Piloting – the use of landmarks, aids to navigation, soundings to navigate a boat while operating along the coast or near land

b.
Chapman
gives a great explanation of piloting as both a science and an art (Chapter 16)
